Referring to the exhibit, which two statements are correct? (Choose two.)
The configuration provided shows two switches configured with Multiple Spanning Tree Protocol (MSTP). The bridge priority values play a crucial role in determining the root bridge for each Multiple Spanning Tree Instance (MSTI). For MSTI 1, DS-1 has a bridge priority of 4k, which is lower than DS-2’s bridge priority of 8k for the same instance. This makes DS-1 the root bridge for MSTI 1. For MSTI 2, DS-2 has a bridge priority of 4k, which is lower than DS-1’s bridge priority of 8k for this instance, making DS-2 the root bridge for MSTI 2.
DS1 - root bridge for msti 1 (vlan 10-19) - due to bridge priority 4k DS2 - root bridge for msti 2 (vlan 20-29) - due to bridge priority 4k
A & B are correct. "The root bridge for each spanning-tree protocol instance is determined by the bridge ID. The bridge ID consists of a configurable bridge priority and the MAC address of the bridge. The bridge with the lowest bridge ID is elected as the root bridge. If the bridge priorities are equal or if the bridge priority is not configured, the bridge with the lowest MAC address is elected the root bridge." https://www.juniper.net/documentation/us/en/software/junos/stp-l2/topics/topic-map/spanning-tree-root-protection.html#id-understanding-bridge-priority-for-election-of-root-bridge-and-designated-bridge
ab is correct
Should be C and D. Bridge priority is to determine which bridge becomes the designated bridge.
